Hi everyone,
I'd like to project two pcas onto one device window.
I plot my first PCA:
biplot(prcomp(t(cerebdevmat)), var.axes=FALSE, cex=c(1,.1),
pc.biplot=TRUE)
Now I'd like to project the features of another PCA onto this graph.
Any suggestions?
I know this is easily done in MatLab but haven't figured it out in R.
Thanks,
Tanya
